RE: [CAD_CAM_EDM_DRO] A little bit of help; Always works!!!

Hi Anthony:

I'm in the same boat as you, and am looking at what it takes to do my own
thing. If I follow Chris Stratton's description, I've chosen the Sherline
4400 lathe and 2000 mill as my hardware. I'll most likely buy the Sherline
kit to attach motors to the devices. I was at Western Garbage in Cleveland
(actually, Electronic Surplus nee Western Salvage) today looking at stepper
motors. I came across some from Sanyo that may do the job at $7.95 each.
I've already searched the web for software. I've got either a Zenith 486
based notebook computer or a Compaq 1075 notebook that will drive the whole
thing. Looking at software, I'll probably first start with Dave Kowalski's
TurboCNC program (especially since it has source code available) and move to
something different if I encounter problems. I'm using Intellicad 2000 to
generate the DXF files and I'm looking for a good program to convert the DXF
to G code to drive TurboCNC. I haven't settled on any motor drivers yet.
From what I've read, the bipolar drives are the "best" but with Sherline as
the mechanical base, the L/R unipolar drivers may work as well. I figure
that, with a little care, I can get something up and running for a couple of
hundred bucks plus the cost of the Sherline N/C kit.

My goal is to be able to make some small parts for model railroad
locomotives. The Sherline tools should handle the size of any parts I'll be
making.

Hi Anthony,

Go for it! If you don't, you'll miss out on a lot of learning. Check
out Camtronics or Gecko for the drivers, CNCpro for a controller
program, and add Sherline's mounts to a Sherline, or the appropriate
mounts for the Taig. As for a "manual", this list is better then a
manual, it's "interactive".

get ready to learn!

like the Taig milling machine or to retro fit one myself. Personally I
would rather build one myself, get a small milling machine and you know do
it myself. But I am worried about the electronics of it and the software
sides of thing!! How have people done this?? Is there any literature that
anyone knows of like a step by step guide to converting a machine?? Any
companies that supply the electric gubins??? And the software?? I start
getting lost in it all?? Should I just buy on of these small CNC machines??
